STREET-LAM P.

fiPECIPICATION forming part of Letters Patent No. 339,884, dated April 13, 1886.

Application filed December 23, 1885. Serial No. 186,542. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT F. B. HEN- MG, of Denver, in the county of Arapahoe and State of Colorado, have invented a new and useful Improvement in Street-Lamps, of

which the following is a full, clear, and exact description.

The object of my invention is to provide certain new and useful improvements in streetlamps,whereby the gas is automatically turned on by swinging up the bottom gate or door to introduce the torch or other light used for igniting the gas.

The invention consists in the construction and combination of parts and details as will be fully described and set. forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a cross-sectional view through the lower part of a lamp provided with my improvement. Fig. 2 is a plan view of the same.

The burner-tube A, of the usual construction, is provided wit-h the cock B, which is also of the usual construction, and is provided on the outer end of its stem O with the ratchet-wheel D. The two levers E are mounted to rock on the stem 0, at opposite sides ot the ratchet-wheel D, and have their swinging ends pivoted to the link F, which is pivoted to the upper surface of the door G, pivoted in the bottom of the lantern-frame J, to swing upward. Between the two levers E the pawl K is pivoted, which rests on the rim of the ratchet-wheel D, and can engage with the teeth of'the same. The door G is provided with the recess L in its inner edge, to permit it to swing upward without interfering with the burner-tube.

The operation is as follows: The lampthe end of the burner, and then the gas is ignited by means of the torch. The gate then swings down without affecting the position of the cock. XVhen the gas is to be shut off, the door G is again swung up in the manner stated, and thereby the cock B is given another quarter-turn and the burner is closed.

My improvement can be applied on any gaslamp and on any burner.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent 1. The combination, with a lamp-frame, a gas-burner, and its cock, of a swinging door on the frame, a lever mounted loosely on the stem of the cock and connected to the door, and intermediate devices between the said lever and cook for turning the latter when the door is opened, whereby provision is made for turning on and off of the gas by the opening of the door, substantially as described.

2. The combination, with a lampframe, a swinging door on the same, a gas burner therein, and its cook, of a ratchet-wheel on the cook, a lever pivoted to the burner and connected to the door, and a pawl pivoted to the lever and engaging the ratcheowheehsubstantially as and for the purpose set forth.

3. The combination, with a lamp-frame, a swing-door on the same, a burner therein,a11d its cock, of a ratchet-wheel on the stem of the cock, levers pivoted on the stem of the cook. a link connected to said levers and door, and a pawl pivoted to said levers and engaging the ratchet wheel, substantially as herein shown and described.

4. The combination, with a lamp-frame, of a swinging door in the bottom part of the same, aratchet-wheel on the stem of the cock of the burner in said lamp frame, levers mounted to swing on the stem of the cook, a link connected with the said levers and with the door, and of a pawl pivoted to said levers and engaging with the ratchet-wheel on the stem of the cock, substantially as herein shown and described.
